The bar where Arizona State University student Jack Culolias was last seen the night he disappeared cannot prove that employees checked the identifications of patrons buying alcohol at a sorority party from which Culolias was thrown out before he later was discovered dead, according to a state investigation.

The Arizona Department of Liquor Licenses and Control’s investigation, released this week to The Arizona Republic, concluded Culolias attended a sorority party at Cadillac Ranch at Tempe Marketplace on Nov. 30, where the 19-year-old freshman drank alcohol and used a credit card to buy an alcoholic beverage.

But the bar was not using its ID log properly that night and can’t prove employees checked any of the IDs of people at the party who bought alcoholic drinks, the report states.

Culolias disappeared that night after he was told to leave the bar at about 11 p.m. because he was urinating on the balcony. He never returned home, and friends reported him missing the next day. On Dec. 16, his body was pulled from an area of the Salt River northeast of Tempe Marketplace.

The Tempe Police Department is awaiting autopsy results from the Maricopa County Medical Examiner’s Office to complete its investigation into what happened that night, police spokesman Sgt. Mike Pooley said.

Investigators will be interested in the toxicology report, Pooley said, and the manner of death, which could reveal if there were any signs of foul play not detected by police officers.

The liquor-license department concluded that the bar committed two violations of failure to follow the identification procedure prescribed by statute, and selling, giving or furnishing an underage person with alcohol, according to the department’s investigation.

Department spokeswoman Lee Hill said the investigation was sent to the department’s compliance unit, which has determined fees and/or other actions that Cadillac Ranch will have to complete based on law, the facts in the investigation and any duplicate violations that have occurred in the last two years. She did not specify what the fees or required actions were, saying the bar must first agree to the terms.

Liquor-department records show the bar has had five incidents dating back to April 2008, including multiple violations of selling, giving or furnishing alcohol to an underage person, failure to follow identification procedures and accepting unauthorized forms of identification. It paid two separate fines of $750 and was given a warning letter for three incidents, records show. The other two were dismissed.

“While it is unfortunate that two individuals used fake identification on the night in question, Cadillac Ranch’s staff complied with state law in checking IDs,” spokeswoman Jennifer Kaplan said. “Cadillac Ranch is working closely with the Compliance Division of the Liquor Department to review the facts in response to the department’s inquiries and to resolve the pending matter. We have no further comment.”

The department’s investigation revealed additional details about the party Culolias attended the night he disappeared.

An ASU sorority rented the outdoor patio/bar area from 8 p.m. to midnight for a “social date night” event in which the sorority would host the party and each member who attended would bring another person, according to the investigation. The group, estimated at about 190 people and a 50-50 split between men and women, arrived around 9:45 p.m. in multiple buses and “it was apparent that most were intoxicated.”

Three security guards checked IDs at the door. Many who bouncers deemed too intoxicated were denied entry, the report states. Of those who were allowed in, everyone under 21 was given red wrist bands, while those over 21 were given neon yellow wristbands. Six security guards handled the patio/bar area.

Surveillance footage shows Culolias bought a Corona beer from the bar at 9:53 p.m. with a credit card, the document said. Ten minutes later he was seen drinking from it and then buying a mixed drink with cash.

Within the first hour after the group arrived, numerous men were escorted out for various reasons, such as taking off their shirts and transferring colored wrist bands, according to the investigation. Cadillac Ranch employees said some of the people with red wristbands were flipping them inside out because then they looked yellow in the bar light. Many were kicked out when staff realized it.

Bar staff said they saw Culolias drink from a friend’s alcoholic beverage, and one said “Jack’s eyes were wide and red and he looked kind of wobbly/out of it,” noting that he was holding onto the handle on the wall, the report states.

Later in the night, several people saw Culolias urinating on the balcony, the document shows. Security was notified and he was escorted out of the bar, where he was seen leaving down the south stairwell. One bouncer said he told Culolias to go to the cabs.

Tempe detectives told the liquor-department investigator that Culolias was wearing a bright yellow wristband on his right wrist when his body was pulled from the river three weeks later, and the only items in his pockets were a small wallet with a fake Hawaii driver’s license and a AAA card, according to the report. The fake license, which investigators determined came from a website that sells fake IDs to college students, had Culolias’ name and photograph, but a different birthday.

Cadillac Ranch’s ID log did not have any Hawaii IDs logged on it, the investigation states. The liquor-department investigator also determined that none of the names of the 46 people who used their credit or debit cards at the bar during the sorority party were on the ID log.

According to state law, an employee who doesn’t log an identification is presumed not to have checked the person’s ID.

Bar receipts also showed that a 20-year-old man, who said he used someone else’s ID to get a yellow wristband, bought 33 alcoholic drinks totaling almost $200 for himself and others, according to the investigation.

Fraternity members who were at the party began changing their stories after the first day, recanting statements that Culolias had used a fake ID to get in, the document states.

The owner believed the legal counsel “for the fraternity is telling everyone involved to not admit anything and not talk to anyone about this incident,” the report states.
